Have you (or your developers) made any changes to the algorithm Pligg uses to determin what is most popular? I had a look at Pligg some months back but dropped it when I saw in the code it ranks stories simply by the date they were published (ie obtained the threshold number of votes to appear on the front page of the site).

Any further significant voting after the story is published to the main page doesn’t effect the weighting of the story. Said story will simply cascade down the rankings as new stories are voted up. (Digg, for example will repromote stories if they are heavily dugg etc etc)

Pligg is a nice ‘shell’ for a Digg-like site, but it lacks an algorithm and for that reason I don’t believe it’s mature enough to use.

If you’ve done any work on this area of your Pligg install could you let the community have a copy of your algorithm?
